I am writting an extension that will be installed as a wildcard script map on Exchange's CAS Role machine. It will be installed on the virtual directory /Microsoft-Server-ActiveSync.

The actual handler on this virtual directory is AirSync.dll. As far as I know, It maintains a network connection with SmartPhone devices (ActiveSync compliant- Window Mobile, iPhone etc.)

I would like to know-

1. Is it possible to install the Wildcard ISAPI Extension, such that It is called on every request it receives from devices, and then safely forward the request to its original handler (AirSync) using HSE_REQ_EXEC_URL ? 2. Will installing an ISAPI Extension on virtual directory /Microsoft-Server-ActiveSync, allow the actual handler to maintain the Network connection with devices ?
